Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622118, here are decompositions:

5 + 31622113 = 31622118
37 + 31622081 = 31622118
71 + 31622047 = 31622118
137 + 31621981 = 31622118
139 + 31621979 = 31622118
239 + 31621879 = 31622118
271 + 31621847 = 31622118
379 + 31621739 = 31622118

Showing the first eight; more decompositions exist.
